The story of the Dornier Do X -- the largest, heaviest, and most powerful aircraft of its time -- a three-deck flying boat with 12 engines, a smoking salon, and sleeping cabins that ultimately became the most ambitious failure of aviation's golden age.

On February 3, 1966, the Soviet spacecraft Luna-9 became the first human-made object to soft-land on the Moon. Sixty years later, space enthusiast Vitaly Egorov spent six months hunting for its exact location using satellite imagery, 3D terrain models, and the panoramas Luna-9 took of itself — and found it.

We interact daily with technologies we don't truly understand — and that gap between familiarity and comprehension is more dangerous than it seems. From fake bomb detectors costing lives in Iraq to NASA being unable to recreate its own moon rocket engine, the cost of technological illiteracy is very real.
Science
The remarkable story of the Soviet M-17 and M-55 stratospheric aircraft — originally designed as Cold War spy balloon interceptors, they set 25+ world records and were repurposed as flying laboratories studying Earth's ozone layer.
Science
Some arguments feel compelling but are structurally broken — they would prove too much, or prove the opposite, or simply restate the conclusion in different words. This article identifies and names the most common patterns of non-working argumentation, with examples from technology debates.
Science
The Sapir–Whorf hypothesis — the idea that the language you speak shapes or limits how you think — has enjoyed a popular revival, but the actual scientific evidence is far weaker and more ambiguous than its enthusiasts claim. This article examines the evidence and the methodological problems.
Science
A hands-on account of building a homemade radio telescope from salvaged satellite equipment for under $115, culminating in the detection of neutral hydrogen emission lines from the Milky Way. The author explores galactic structure through Doppler-shifted frequency profiles from a backyard shed.
Science
The story of the An-22 Antey, the world's largest turboprop aircraft ever built, from its dramatic first flight in 1965 to its retirement in 2024 — including 41 world records, service in Afghanistan, and unrealized nuclear-powered variants.
Science
A thorough introduction to radar — how radio waves detect targets, why antennas work the way they do, and what physical limits govern the design of every radar system ever built. The first in a four-part series tracing radar from its 1904 origins through WWII breakthroughs to modern Doppler and FMCW systems.

A raw file from a camera sensor looks nothing like a photograph — it is a grayscale grid of integers with a narrow dynamic range, a mosaic color pattern, and nonlinear brightness. Here is the step-by-step process that turns it into an image your eyes can read.
Science
A pattern doodled in a school notebook became a wall decoration, then a 12-year mystery, then a journey through L-systems, matrix number bases, and the strange mathematics of why the construction only works in dimensions 1, 2, and 4.
Science
The Ka-22 convertiplane promised to combine a helicopter's vertical takeoff with an airplane's speed and range, setting eight world records before two fatal crashes ended the program in 1964.
